Question

While demonstrating an experiment to show whether the given liquid conduct electricity or not to class VIII students, the teacher reminded everybody that one should not conduct an experiment with the electric supply from the mains or a generator or an inverter. They should use electric cells for the activity.
(a) Do liquids conduct electricity?
(b) Why we should not use an electric source from the main generator or an inverter?
(c) What values do we get from

Answer 1

Answer:

Yes, Conduction of liquids depends on the ability of liquids to form ions. Some liquids such as oil or alcohol do not form ions and do not conduct electricity. ... The acetic acid separates into ions in water. So its solution conducts electricity.

Answer 2

Question

While demonstrating an experiment to show whether the given liquid conduct electricity or not to class VIII students, the teacher reminded everybody that one should not conduct an experiment with the electric supply from the mains or a generator or an inverter. They should use electric cells for the activity.

(a) Do liquids conduct electricity?

(b) Why we should not use an electric source from the main generator or an inverter?

(c) What values do we get from

Answer:

a) Yes, liquids which are solutions of acids, bases, and salts conduct electricity. Other liquids such as oil, alcohol, sugar solution, and pure water do not conduct electricity.

(b) Current flowing from mains, generator or an inverter is very large. So to avoid the chances of electrocution and short-circuit we must use cells for experiments.

(c) We get the awareness of not using main electric supply and precaution to be followed while doing the experiment
